First Pass JLPT: N5–N1 practice exams with immediate feedback, a comprehensive inline dictionary, and nuance comparisons

Hi everyone,

First Pass JLPT (https://firstpassjlpt.com) is a JLPT practice exam system I’ve been building over the past year. It gives you immediate feedback on every question, a click-to-define inline dictionary, and side-by-side comparisons for kanji, readings, vocabulary, and grammar that are easy to confuse.

When I was preparing for N2 back in 2023, I kept hitting a wall with paper practice books. I’d flip between the question, the answer key, and a separate dictionary, lose my place, and sometimes wouldn’t know why an answer was wrong. It felt like all of this should just be on one screen.

The System

  • Immediate feedback on every question. Not just right or wrong. The feedback explains why the right answer is right, and when there’s a close-but-wrong option (visually similar kanji, similar readings, close-meaning vocabulary, similar grammar), it shows you the difference instead of leaving you to guess.

  • Comprehensive inline dictionary. Click any word while practicing. Entries are detailed, not just one-line definitions.

  • Nuance comparisons. Side-by-side explanations for kanji, readings, vocabulary, and grammar that are easy to confuse. Examples: 持 vs 待 vs 時 (same right-side component 寺, three different left radicals), 暑 vs 署 (differ only in the top radical: 日 vs 罒), 思う vs 考える, ~ながら vs ~つつ, ほど vs くらい.

  • N5 through N1 coverage. 150 exams across the five levels, 8,000+ total questions. Mondai structure follows the JLPT exam format for vocabulary, grammar, and reading sections, with listening planned as a future feature.

The Interface

Access

First Pass JLPT is free for the first 5 exams of each level, capped at 20 practice questions a day. For most people studying alongside other materials, that should be more than enough practice, and while there are premium features, upgrading is completely optional.

About the Site

The site is currently built to be a practice and review tool, not a replacement for a textbook or course. This would be best paired with whatever main study you already use.

The questions and content are modeled on the JLPT mondai structure for each section, but none of it comes from real JLPT exam material. I’m actively working on improving the content, the feedback, and the experience itself.

Roadmap

I do plan to eventually make content for the listening section and other features if the project picks up support. I want to make sure that all of the content is legitimately good, but native voices and dialogue that align with what you’d hear on the actual test will take more time and careful planning.

Feedback

If you’re preparing for the JLPT, I’d love for you to give it a try. Please reply here with questions, feedback, or comments.

Thank you for reading!

Oh very cool, will definitely give it a try!

Real quick, I noticed a bug that whenever you answer a question it immediately defaults to “NOT QUITE” status for a brief millisecond. For example, the correct answer is 今日, but for a brief moment it said not quite.

Pretty useful site to comb through!

Thank you for your feedback! I really appreciate it.
I was able to replicate the issue and deploy a fix for the bug. Please don’t hesitate to reach out if you run into anything else.

This is a cool site!

Might be nice to add an option to enlarge the text though; I’ve got pretty good eyesight but I was straining quite a bit to see the differences between some of the text sometimes.

The underline on the answers also made some of the characters hard to read because of the lack of distance.

Really cool website though!

Thank you for the feedback! I’ve increased the text size for the exam interface and dictionary entries and made the underline transparent for better visibility. I might make a dedicated text size option in the future and work more on the UI, but this should help in the meantime.

Thank you again for taking the time to let me know!
